[jdk8u-dev] RFR: 8269850: Most JDK releases report macOS version 12 as 10.16 instead of 12.0 [v3]

[Olga Mikhaltsova]

> I'd like to backport JDK-8269850 to jdk8u in order to fix the incorrect version detection for macOS.
> 
> The patch applied manually due to the location difference:
> src/java.base/macosx/native/libjava/java_props_macosx.c (source)
> jdk/src/solaris/native/java/lang/java_props_macosx.c (destination)
> But it's small and low risk. The changes are related only to one function void setOSNameAndVersion(..) within the single file. The patch is identical to the original one.
> 
> Tested with a simple test printing the OS version on macOS Monterey:
> 
> public class Main {
>     public static void main(String[] args) {
>         System.out.println(System.getProperty("os.version"));
>     }
> }
